We report a case of adenocarcinoma arising from a sacrococcygeal mature teratoma in an adult female. A 62-year-old female was diagnosed with a presacral tumor 10 years ago. Pelvic computed tomography (CT) demonstrated a presacral heterogeneous tumor, containing multiloculated cystic area and enhanced solid component with calcification. Percutaneous needle biopsy for the solid component of the t...

Sacrococcygeal teratoma (SCT) is the most common congenital tumor in neonates. SCT may be benign (mature and immature) or malignant. Malignancy is rare in SCT diagnosed before 2 months of age. Here, we describe a neonate having a mature teratoma with a focus of malignant yolk sac tumor within and the difficulties faced in its management.

Teratomas are tumors containing tissues derived from all three germinal cell layers. Most teratomas arise in the sacrococcygeal region, with a reported incidence of 1/40,000 births. During labor, severe dystocia may occur in infants with large tumors if delivered vaginally, with an extremely high fetal morbidity and mortality rate. Reported is a case of a large congenital sacrococcygeal teratom...

The occurrence of a fetal tumor is rare, 50% of all fetal tumors being sacrococcygeal teratomas. Prenatal diagnosis of this condition is important for the monitoring of the affected fetuses and for establishing the mode and time of delivery. We describe two cases of fetal sacrococcygeal teratoma diagnosed by 2D- and 3D-ultrasound. Three-dimensional ultrasound proved to be useful both in the dia...

A male baby of 2.6 kg was born to Gravida2Para0Abortion1 mother through normal vaginal delivery at 33 weeks of gestation. Baby had normal Apgar score of 8/9/9 at one, five and ten minutes respectively. At birth baby was noticed to have large swelling in the sacrococcygeal region which was approximately having the size of 10*2 cm, with solid consistency and erythematous.

Background: Neonatal tumors are usually prenatally diagnosed or within the irst 30 days of life. The true incidence ofneonatal tumors is unknown as a great number of pregnancies with a prenatally diagnosed mass result in stillbirth ormiscarriage. Most solid neonatal tumors are benign whereas less than 50% of neonatal neoplasms are malignant;however, some tumors with malignant ...
